On the other hand, the secular West and East Asia has very low fertility and a rapidly aging population. The demographic disparity between the religious, growing global South and the aging, secular global North will peak around 2050. In the coming decades, the developed world's demand for workers to pay its pensions and work in its service sector will soar alongside the booming supply of young people in the third world. Ergo, we can expect significant immigration to the secular West which will import religious revival on the back of ethnic change. In addition, those with religious beliefs tend to have higher birth rates than the secular population, with fundamentalists having far larger families. The epicentre of these trends will be in immigration gateway cities like New York (a third white), Amsterdam (half Dutch), Los Angeles (28% white), and London, 45% white British.

Global trends are inevitably going to impact the Western World

Professor Eric Kaufmann, who is an agnostic, told
a secular audience in Australia: "The trends that are happening
worldwide inevitably in an age of globalization are going to affect us."
As early as 2020/2021, Western countries will see a significant
reversal of secularism/atheism/agnosticism and that trend will
accelerate.
